NSX configuration maximums
Let's have a look at what the NSX configuration maximums are. VMware has not published an official document, so the following limits listed were gathered by reviewing NSX documentation and online research. Some websites that contributed include www.vmguru.com.
Some of these limits are hard limits while most of them are soft limits, beyond which VMware does not support such configurations. For example, if you exceed the number of concurrent connections per Edge gateway, it will affect your gateway's performance, but won't cause it to halt or reject new connections. The hard limit verses soft limit documentation is not explicitly published, but VMware NSX support can clarify if needed. The chances are that you will scale out your environment before reaching these maximums.
The maximums for NSX follow.
Note
NSX 6.2 is the current NSX version as of this writing.
Configuration maximums can differ based software release. Always refer to the most up-to-date documentation to ensure accuracy.
